Study of the Effects of Waste Glass Additives on the Properties and Compliance level of Fired Ceramic Masonry Bricks

Abstract

The current study reports the effects of waste glass additives on the properties and compliance level of fired ceramic masonry bricks. In the course of producing durable bricks for masonry, waste glass powder sieved to 150 μm was added to clay, mixed with water and fired to 1000°C. The effects of the waste glass addition were investigated by subjecting 242 ceramic bricks produced to physical, mechanical, and thermal tests. Their morphological behaviour was thereafter examined. From the results obtained, the physical and mechanical properties were improved as waste glass content increased in the samples. Values of properties obtained were compared with existing standard values for bricks and it was observed that compliance level at 0% waste glass was 63%, at 10% waste glass addition, it was 75% and at 15% to 40% waste glass addition, compliance was 100%. Therefore, it was concluded that waste glass addition to bricks improved the properties of bricks for construction purpose.
